Dear Elmaestro and Helmut,

I like to correct what I have said about lme() with NA. We can use lme(..., na.action=na.exclude) if there are some NA in dataset. Looks like this option can avoid crash if we do not omit NA. Sounds great.

❝ • any NA must be removed (as the entire period) first before doing lme(); otherwise, it will crash.[/list] So there is no way to compare the difference.
